Title: An improved single-acting pneumatic motor
IPC: F16N13/16
Filed: 1954-08-13
Abstract: 750,586. Engine valve gear. SOC. AUTOLUBE. Aug. 13, 1954 [June 1, 1954], No. 23545/54. Class 122(2) In a pneumatic motor, particularly for operating a lubricating appliance, the admission and exhaust valves 28a, 28b and 23 respectively are actuated by a sleeve 21 co-axial with the motor piston 7 and having a lost motion connection with a member 14 which is also co-axial with the piston 7 and has a lost motion connection therewith and is moved rapidly towards each end of its movement by a snap-action mechanism comprising a double-cone projection 15a, 15b co-operating with a resilient torus 16. The exhaust valve 23 is attached to the sleeve 21 which has a shoulder 26 that co-operates with the admission valves 28a, 28b and is secured by a pin 22 with a rod 19 having a head 20 slidable in a bore in the member 14 which slides in a fixed guide bush 5 and is secured by a pin 13 to a rod 10 having a head 11 slidable in the closed bore of a hollow rod 8 integral with the piston 7. The torus 16 is a garter spring and is held so as to be axially fixed but radially free between parallel surfaces 17 and 18. In operation, in the position shown in Fig. 1 air supplied through inlet 29 flows through the admission valves and past the garter spring 16 to the underside of the piston 7 which is thereby raised against the resistance of a return spring (not shown). When the head 11 contacts the shoulder 12, formed at the bottom of the bore in rod 8, the member 14 is moved upwards, the cone 15a expanding the spring 16 until the common base of the projection passes the spring after which the latter contracts along the cone 15b and moves the member 14 rapidly upwards and, as the internal shoulder of the bore in the member contacts the head 20, the sleeve 21 is also moved suddenly upwards to open the exhaust valve 23 and allow the admission valves 28a, 28b to be closed by their springs 30. The piston is then returned by its spring, exhaust taking place through the conduits 24, 25 until the closure plug 9 contacts the head 11 and the snap-action mechanism is again operated to close the exhaust valve and open the admission valves and the cycle recommences. In a modification the double cone projection is formed on the cylinder cover 2 and the garter spring is carried in a groove in the member 14. Specifications 638,703 [Group XXVIII] and 689,854 are referred to.

Abstract: 223,240. British Thomson-Houston Co., Ltd., (Assignees of Marcellus, F. S.). Oct. 9, 1923, [Convention date]. Clocks combined with electric meters; chronoscopes.-A current meter and ampÚre-hour meter are combined with a clock, particularly for use on a motor-car. A disc 15, Fig. 3, is driven at a constant speed by the clock, for example by the minute-hand shaft. Frictionally driven by the disc 15 is a disc 17, in a plane at rightangles thereto, mounted on a permanently magnetized steel shaft 18 provided with non- magnetic extensions 22, 23. The shaft 18 is mounted in bearings 19, 20 in a non-magnetic frame 21 and is slidable axially under the influence of solenoids 22<1>, 23<1> in series with the dynamo 25 and storage battery 24, being normally held central by springs 26, 27. A long pinion 29 engages a gear-wheel 30 driving a counting-gear 28, Fig. 4, for indicating the charge in the battery 24. Current from the dynamo 25 in the direction for charging the battery 24 causes the shaft 18 to slide axially to the right, the disc 17 being therefore rotated bv the dies 15 in the direction causing increase of reading of the counter at a speed proportional to the axial movement. Current from the battery 24 in the discharging direction causes axial motion of the shaft 18 to the left, thereby causing it to be rotated in the reverse direction. In order to allow for the efficiency of the battery, the spring 26 may be stronger than the spring 27, so as to make the aggregate rotation of the shaft 18 zero for a complete cycle of charge and discharge. A thin-edged disc 34 mounted on the shaft 18 co-operates wit'h a scale 33, Fig. 4, to indicate the current flowing. In order to indicate the time of charging, an auxiliary pointer 36 may be driven by, but adjustable with respect to, either the hour or minute hand of the clock so that it mav be set to 12 o'clock when battery charging is started.

Abstract: 1,142,252. Electrically heated platens. E. W. BLISS CO. 31 May, 1966 [17 June, 1965], No. 24150/66. Heading H5H. [Also in Divisions B3 and G1] A hot sizing press has upper and lower platens B, C, Fig. 1 (not shown), heated by resistance heaters arranged in series-connected pairs H1, H2, Fig. 4, and means 13, 14 are provided to test the heaters and identify any burned-out heater. The press which is actuated hydraulically, is of particular use in hot die pressing of high-alloy steel or titanium sheets used in aerospace work. The dies are mounted on carriages which move them between the press and ovens arranged on opposite sides thereof. For heating the platens, the pairs of resistance heaters are connected in star or preferably in delta across a three-phase supply R1, R2, R3, Fig. 5 (not shown). The heaters are connected individually to the contacts 13 of banks II, III of a stepping switch whose collectors 14 are automatically driven stepwise by a motor at about eight steps per second. A burned-out heater such as H1 will be detected by giving a no-voltage signal across its mating heater H3. A pair of counting tubes 36, 37 connected to further banks VI, VII of the stepping switch show which heaters are being tested and a defective heater causes the switch to be stopped with the heater identified on the tubes. Another embodiment is described, Fig. 6 (not shown), for checking up to ninetysix heaters using an eight-bank stepping switch.
